Applies  to  veh icles: w ith  Hom eli nk ® universal  remote  control 
General  information 
The Homelink ® feature  can  learn  the up to  three  radio 
frequency  codes  for  most  current  transmitters  used  for 
operating  garage  doors,  estate  gates,  home  or outdoor 
lighting  systems,  and  other  devices. 
You  must  first  program  the  Homelink ® transm itter before  you  can 
use  the  system=> 
page 170, "Programming  the Home link® trans
mitter". 
I n  order  to  program  the  Homelink ® transmitter  for  devices  utilizing 
rolling  code,  a  second  person on  a  ladder  who  can  safe ly reach  the 
garage  door opener  motor is recommended. It is also  necessary  to 
locate the  "learn"  button  on  your  garage  door  opener  motor.  Refer  to 
the  operating  instructions  for  the  opener,  as  the  location and  color  of 
this  button  may  vary  by  manufacturer. 
You can  still  use  the original  remote  control  for  the device  at  any 
time. 
& WARNING 
•  Never use the  Homelink'"' transmitter  with  any garage  door 
opener  that  does have not  the  safety  stop and  reverse feature  as 
required  by federal  safety  standards. This includes any  garage 
door opener  model  manufactured  before  Aprill,  1982. 
•  A garage  door opener  which  cannot  detect  an object,  signaling 
the  door to  stop and  reverse does not  meet  current  federal  safety 
standards.  Using  a garage  door opener  without  these  features 
increases risk of  serious injury  or death. 
Controls  and  equip 
ment  Safety  first 
& WARNING 
(continued) 
• For safety  reasons never  release the  parking  brake  or start  the 
engine  while  anyone  is  standing in front  of  the  vehicle. 
•  A garage  door  or  an estate  gate  may  sometimes be set  in 
motion  when  the  Homelink ® remote  control  is being 
programmed.  If  the  device is repeatedly  activated,  this  can over
strain  motor  and  damage  its  electrical  components  -an  over
heated  motor  is  a fire hazard! 
•  To avoid  possible  injuries  or  property  damage,  please  always 
make  absolutely  certain  that  no persons or objects  are  located  in 
the  range  of  motion  of  any  equipment  being  operated.

If you  do  not  drive  your  vehicle over  a period  of several  days  or weeks, 
electrical  components  are  gradually  cut  back  or  switched  off. This 
red uces  energy  consumption  and  maintains  starting  capability  over  a 
longer  period. 
Take  into  consideration  that  when  you  unlock your  vehicle,  some 
convenience  functions, such  as  the  remote  key  or power  seat  adjust
ment,  may  not  be  avai lab le.  The  convenience  functions  wi ll  be  ava il
able  again  when  you  turn  on the  ignition  and  start  the  engine. 
With  the  engine  turned  off 
If you  listen  to  the  radio,  for  example, with the  engine  turned  off  o r 
use  other  MMI functions,  the  battery  is being  discharged. 
If  starting  capability  is jeopard ized  due  to  energy  consumption,  the 
following  warning  appears  in the  MMI  display: 
Please  start engine,  otherwise  system  will  switch  off  in 
3  minutes . 
The  warning  indicates that  the  system  will  be  turned  off  automati
cally after  3  minutes.  If  you  wis h  to  continue  using the  funct ions, you 
have  to  start  the  engine. 
With  the  engine running 
Although  electrica l energy  is generated  when  the  vehicle  is being 
dr iven,  the battery  can  become discharged.  This happens  mostly 
when  little  energy  is being  generated  and  a  great  deal  consumed  and 
the  battery's  state  of charge  is not  optimal. 
To  bring  the  energy  balance  back into equilibrium,  consumers  which 
req uire  especially  large  amounts  of  energy  are  temporarily  cut  back 
or  switched  off . H eating  systems  in  particular require  a  great  deal  of 
energy.  If  you  notice,  for example,  that  the  heated  seats*  or  the 
heated  rear  window  are  not  heating,  they  have  been  temporarily  cut 
back  or  switched  off.  These  systems  will  be ava ilable  again  as  soon  as 
the  energy  ba lance  has  been  restored.  You will  also 
notice that  engine  idle speed  has  been  increased 
slightly.  This  is normal  and  not  a  cause for  concern.  By  increasing 
engine  idle  speed  the  addit ional  energy  required is generated  and  the 
battery  is charged. • 
Driver  notification  in  the  instrument 
cluster  display 
If  battery  powe r drops  into the range  where  it  can limit  the  ability  of 
the  engine  to  start,  this  is shown  in the  instrument  cluster  display 
w ith  the  following  driver  message: 
1 Low battery  charge: battery will  be charged  while  driving 
This  notification  reminds  you  that  the  starting  capability  of  the 
eng ine may  be  limited.  As soon  as you  start  driving again, the  battery 
will  be  recharged  and  the notification  will  go  out. 
Driver  notification  appears and  goes  out  again 
If  this  driver  notification  appears  after  the  ignition  is turned  on  or 
wh ile  driving  and  it goes  out  again  after  a  while,  the  battery  has  been 
adequately  recharged. 
Driver  notification  appears  and does  not  go  out 
again 
If  this  dr iver  not ificat ion  appears  after  the  ign it ion  is turned  on  or 
whi le  driving  and  does  not  go  out  again,  the  battery's state  of  charge 
is  not  in the  optimal  range. Starting  ability  is restricted . Have  the 
battery  checked  as  soon  as  possible  at  a dealership.

Brake  fluid  will  damage  the  paint  of  your  vehicle. 
Because  of  the problem  of  proper  disposal  of  brake  fluid  as  well  as 
the  special  tools  required  and  the  necessary  expertise,  we  recom
mend  that you  have  the brake  fluid  changed  by your  authorized  Audi 
dealer. • 
Battery 
General  information 
Under normal operating  condit ions,  the battery  in your  Aud i does  not 
need  any  maintenance.  With 
high outside  temperatures  or  long  daily 
drives  we  recommend  that  you have the  electrolyte  level  checked  by 
a  service  facility.  The electrolyte  level  should  also  be checked  each 
time  the  battery is  charged~ 
page 290. 
Have the  battery  checked  when  you  take  your  vehicle  in  for service. 
You  are well  advised  to replace  a  battery  that  is older than  5 years. 
With  certain  types  of  a irbag  deployment,  the  battery  is disconnected 
from  the  vehicle  electrical  system  for  safety  reasons=> 
& in "Repair, 
care  and  disposal  of  the airbags"  on 
page 209. 
Disconnecting  the  battery  terminals 
Some  vehicle  functions  (power  window  regulators,  for  example)  are 
lost  if the battery terminals  are  disconnected.  These  functions  have 
to  be  relearned  after  the  battery  terminals  are  connected  aga in.  To 
prevent  this,  the  battery  should  only  be disconnected  from  the 
vehicle  electrical  system  when  absolutely  necessary  for  repairs. 
Vehicles  not  driven  for  long  periods 
If you  do  not  drive  your  veh icle  over  a  period  of  severa l days  or weeks, 
electrical  components  are  gradually  cut  back  or  switched  off.  This 
reduces  energy  consumption  and  maintains  starting  capability  over  a 
longer  period~ 
page 247. 
Take  into  consideration  that  when  you  unlock your  vehicle,  some 
convenience  functions,  such  as  the master  key  remote function  or 
power  seat  adjustment,  may  not  be  available.  The  convenience  func
tions  will  be  available  again  when  you  turn  on  the  ign ition  and  start 
the  engine. 
Winter  operation 
During  the  winter  months,  battery  capacity  tends  to  decrease  as 
temperatures  drop. This  is because  more power  is  also consumed 
while  starting,  and  the  headlights,  rear  window  defogger,  etc.,  are  used  more  often . 
Avoid unnecessary  power  consumpt ion,  particu larly  in city  traffic  or 
when  traveling  only  short  distances.  Let your  authorized  Audi  dealer 
check the  capacity  of  the  vehicle  battery  before  w inter  sets  in 
=> page 290.  A well  charged  battery  will  not  only  prevent  starting 
problems  when  the weather  is cold,  but will  also  last  longe r. 
(I] Tips 
If  your  veh icle  is  left  standing  for  several  weeks  at extreme ly  low 
temperatures,  the  vehicle  battery  should  be removed  and  stored 
where  it will  not  freeze. This  will  prevent  it  from  being  damaged  and 
having  to  be  replaced.•
